At 5W, this bulb is suited to accent lighting, decorative pendants, or secondary light sources in a layered scheme. At 10–15W, it works as a primary light source in smaller rooms — a bedroom, hallway, or home office. At 20–30W, it delivers high output comparable to a 150–250W incandescent equivalent, making it appropriate for large living rooms, open-plan spaces, or commercial settings where strong, even illumination is needed from a single E27 socket. The warm white option (2700–3000K) produces a relaxed, amber-toned light suited to residential interiors; cool white (6000K) is sharper and better suited to task-focused or commercial environments. The colour temperature is fixed at purchase. These bulbs are not dimmable.\u003c\/p\u003e\n\n\u003cp style=\"font-size:15px;line-height:1.8;margin:0 0 36px 0;color:#121212;\"\u003eA key advantage of this range is the ability to match the bulb’s output precisely to the fitting’s maximum wattage rating — always check the maximum wattage marked inside your fitting before selecting. Using a bulb above the fitting’s rated maximum is a safety risk and may damage the fitting. At 10,000 rated hours, each bulb will last approximately seven years at four hours of daily use.

Always check the maximum wattage rating marked inside your fitting — never exceed it, regardless of the bulb type.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails class=\"ld-faq\" style=\"border-bottom:1px solid rgba(18,18,18,0.08);padding:14px 0;\"\u003e\n  \u003csummary style=\"display:flex;justify-content:space-between;align-items:center;cursor:pointer;list-style:none;\"\u003e\n    \u003ch4 style=\"font-size:14px;font-weight:600;color:#121212;margin:0;\"\u003eIs a 30W LED bulb safe to use in a standard E27 fitting?\u003c\/h4\u003e\n    \u003cspan style=\"color:#C9A84C;font-size:18px;font-weight:300;\"\u003e+\u003c\/span\u003e\n  \u003c\/summary\u003e\n  \u003cp style=\"font-size:14px;line-height:1.8;color:rgba(18,18,18,0.65);margin:10px 0 0 0;\"\u003eIt depends on the fitting’s rated maximum wattage. Most standard domestic pendants and ceiling roses are rated for up to 40–60W, so a 30W LED is within range. However, some decorative or vintage-style fittings have lower ratings (25W or less). Always check the label inside the fitting or the product specification before installing a high-wattage bulb. LED bulbs generate less heat than incandescent equivalents of the same wattage, which reduces thermal risk — but the electrical rating of the fitting still applies.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cdetails class=\"ld-faq\" style=\"border-bottom:1px solid rgba(18,18,18,0.08);padding:14px 0;\"\u003e\n  \u003csummary style=\"display:flex;justify-content:space-between;align-items:center;cursor:pointer;list-style:none;\"\u003e\n    \u003ch4 style=\"font-size:14px;font-weight:600;color:#121212;margin:0;\"\u003eAre these bulbs dimmable?\u003c\/h4\u003e\n    \u003cspan style=\"color:#C9A84C;font-size:18px;font-weight:300;\"\u003e+\u003c\/span\u003e\n  \u003c\/summary\u003e\n  \u003cp style=\"font-size:14px;line-height:1.8;color:rgba(18,18,18,0.65);margin:10px 0 0 0;\"\u003eNo — these bulbs are not dimmable.

As a rough guide: a 20W LED produces light comparable to a 150–175W incandescent; a 30W LED is broadly equivalent to a 200–250W incandescent. These are approximate figures — actual lumen output varies by manufacturer and chip type.

In a fully sealed or airtight enclosure, this can reduce the bulb’s lifespan and, in extreme cases, cause overheating. For enclosed fittings, we recommend using the lowest wattage that meets your light level requirements, or choosing a bulb specifically rated for enclosed use. The 5W and 10W options are generally safer in enclosed fittings than the 20W or 30W variants.\u003c\/p\u003e\n\u003c\/details\u003e\n\n\u003cp style=\"font-size:13px;color:rgba(18,18,18,0.45);border-top:1px solid rgba(18,18,18,0.08);padding-top:20px;line-height:1.8;margin:0;\"\u003e\n  Browse the full \u003ca href=\"https:\/\/lighting-dublin.com\/collections\/led-bulbs\" style=\"color:#121212;font-weight:700;text-decoration:underline;text-underline-offset:3px;\"\u003eLED Bulbs collection\u003c\/a\u003e or read our \u003ca href=\"https:\/\/lighting-dublin.com\/blogs\/news\/lighting-advice-ireland-2026\" style=\"color:#121212;font-weight:700;text-decoration:underline;text-underline-offset:3px;\"\u003elighting advice guide 2026\u003c\/a\u003e. \u003ca href=\"https:\/\/lighting-dublin.com\/policies\/shipping-policy\" style=\"color:#121212;font-weight:700;text-decoration:underline;text-underline-offset:3px;\"\u003eFree delivery on orders over €50.\u003c\/a\u003e \u003ca href=\"https:\/\/lighting-dublin.com\/policies\/refund-policy\" style=\"color:#121212;font-weight:700;text-decoration:underline;text-underline-offset:3px;\"\u003e30-day returns.\u003c\/a\u003e\n\u003c\/p\u003e","brand":"Lighting Dublin","offers":[{"title":"5W \/ Warm White","offer_id":50075414200557,"sku":"4000882617627-5W-Warm White","price":40.0,"currency_code":"EUR","in_stock":true},{"title":"5W \/ Cool White","offer_id":50075414233325,"sku":"4000882617627-5W-Cold White","price":40.0,"currency_code":"EUR","in_stock":true},{"title":"10W \/ Warm White","offer_id":50075414266093,"sku":"4000882617627-10W-Warm White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"10W \/ Cool White","offer_id":50075414298861,"sku":"4000882617627-10W-Cold White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"15W \/ Warm White","offer_id":50075414331629,"sku":"4000882617627-15W-Warm White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"15W \/ Cool White","offer_id":50075414364397,"sku":"4000882617627-15W-Cold White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"20W \/ Warm White","offer_id":50075414397165,"sku":"4000882617627-20W-Warm White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"20W \/ Cool White","offer_id":50075414429933,"sku":"4000882617627-20W-Cold White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"30W \/ Warm White","offer_id":50075414462701,"sku":"4000882617627-30W-Warm White","price":49.0,"currency_code":"EUR","in_stock":true},{"title":"30W \/ Cool White","offer_id":50075414495469,"sku":"4000882617627-30W-Cold White","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0789\/4600\/9325\/files\/lot-de-4-ampoules-e27-a-led-5w-a-30w.jpg?v=1780732689","url":"https:\/\/lighting-dublin.com\/products\/e27-led-bulb-5w-to-30w-warm-cool-white","provider":"Lighting Dublin","version":"1.0","type":"link"}
